What is employee turnover and why does it matter for businesses?
Employee turnover
Employee turnover tracks how many people leave a company during a set time frame, usually over the course of a year. It’s one of the most common ways organizations measure workforce stability. Turnover shows up in two ways—voluntary and involuntary. Voluntary turnover is when an individual chooses to move on, whether for a better opportunity, a career change, or personal reasons. Involuntary turnover, on the other hand, occurs when the employer makes the call for reasons such as restructuring and performance issues.
Let’s take a closer look at what employee turnover is and its impact on an organization.
What are the causes of employee turnover?
People leave jobs, or are let go, for a number of reasons. Here are some of the most common causes of turnover:
- Payroll problems: Late, inaccurate, or difficult-to-track paychecks quickly erode trust in the company. When pay feels unreliable, people start looking for employers who handle compensation more consistently.
- Lack of appreciation: Contributions that go unnoticed or unrewarded make work feel thankless. In these situations, individuals seek out organizations that actively recognize and celebrate achievements.
- Few advancement opportunities: Limited promotions and career development programs can make growth feel out of reach. This lack of progress pushes people to companies that invest in long-term success.
- Poor benefits packages: Weak benefits, like health coverage and retirement options, may leave workers feeling unsupported. Better perks elsewhere often convince them to make a career change.
- Work-life imbalances: When people work consistently long hours with little flexibility, they typically begin to feel burnt out. To protect their well-being, employees may choose to leave and find a company that respects personal time.
- Damaging workplace culture: Toxic management and unhealthy team dynamics create disconnection and stress. People in these environments usually search for healthier and more supportive organizations.
How to calculate employee turnover: 3 steps
Turnover can affect morale, productivity, and even profits, so leaders often want a clear number to track. The good news is that calculating turnover isn’t complicated. Here’s how to do it step by step.
1. Count employee departures
Start by adding up the number of employees who left your organization during the time period you’re measuring. This includes both voluntary resignations and involuntary departures, like layoffs and terminations.
2. Calculate the average workforce
Next, figure out the average size of your workforce during the same period. Add the number of employees you had at the beginning to the number at the end, then divide by two. This keeps your calculations fair even if your headcount fluctuates.
Formula: Average number of employees = (beginning headcount + ending headcount) ÷ 2
3. Determine the turnover percentage
Take the number of employees who left and divide it by the average workforce size. Multiply the result by 100 to express the turnover rate as a percentage. Here is the formula:
Turnover rate = (employees who left ÷ average number of employees) × 100
For example, if a company starts the year with 50 employees and ends with 100, the average workforce size is 75. If 15 employees left during that year, the turnover rate would be 20%.
(15 ÷ 75 = 0.2 → 0.2 × 100 = 20%)
Tips to analyze your organization’s turnover rate
Once you calculate your turnover rate, the real insight comes from interpreting what it says about your workforce. A good starting point is asking what a high turnover rate is in your industry, since numbers that seem elevated in one field may be typical in another. Tracking the figure over time to see whether it's increasing, decreasing, or holding steady will give you a better sense of long-term patterns.
You can also break the figure down by department or location to uncover areas that may need closer attention. It also helps to distinguish between voluntary and involuntary departures, since employees leaving on their own often point to issues with pay, culture, and advancement. On the other hand, company-driven exits can reflect challenges with hiring and performance expectations.
3 ways to reduce employee turnover
Employees want to feel connected, supported, and motivated to grow. Here are three practical ways to build that kind of environment.
1. Start retention early
Retention isn’t something to think about after an employee has been with you for years — it should begin on their very first day. A strong onboarding experience sets the tone for how people see the organization. Done well, it goes beyond paperwork by clarifying the company’s mission, showing where each role fits in, and highlighting the impact new hires can make from day one.
2. Recognize and reward often
People want to know that their contributions matter, and recognition plays a huge part in keeping morale high. When managers take the time to call out wins and say thank you, it creates a culture where people feel valued and supported. In turn, they’re more motivated to do their best work than those who feel overlooked.
3. Support work-life balance
Competitive pay and strong benefits matter, but people also weigh whether they can balance their personal and professional lives. Flexible schedules and perks like travel stipends and wellness allowances are just some of the ways companies can encourage loyalty. When individuals feel cared for both at work and at home, they’re more likely to stay engaged and grow with the company.

FAQ’s
What is a good employee turnover rate?
A “good” employee turnover rate depends on your industry, role mix, and growth stage, but many organizations use annual benchmarks to sanity-check what they’re seeing. As a general rule of thumb, rates under 10% are often considered strong retention, 10–15% is commonly viewed as “normal” in many professional sectors, and anything consistently above 20% is a red flag worth investigating. The more important move is to compare like-for-like (same job family, manager, location, and tenure band) so you don’t end up normalizing avoidable churn just because your company happens to be scaling fast.
Employee turnover vs. attrition: what’s the difference?
People use the words interchangeably, but they’re not the same in practice. Turnover is the broad measure of employees leaving, whether you backfill them or not, and it typically includes both voluntary exits and involuntary exits. Attrition is usually used to describe headcount shrinking over time because roles aren’t replaced after someone leaves, which is common during hiring freezes, restructures, or intentional downsizing. If you’re trying to understand workforce stability, turnover tells you about churn, while attrition tells you about your net headcount plan and whether teams are quietly being asked to do more with less.
What are the different types of employee turnover (and which ones should you worry about)?
Beyond voluntary and involuntary turnover, it helps to classify exits by impact and preventability. Functional turnover is when low performance or poor fit leaves the organization, which can be healthy if it’s handled fairly and doesn’t become a revolving door. Dysfunctional turnover is when strong performers or critical roles leave, which tends to show up as missed deadlines, customer risk, and manager burnout. You can also separate avoidable turnover, where the company could have acted differently, from unavoidable turnover tied to life events like relocation or returning to school. This lens keeps you from chasing a lower turnover number at all costs, and instead focuses you on the exits that actually harm performance and culture.
What’s the “opposite” of employee turnover—and is that always a good thing?
The opposite concept is employee retention, or sometimes “stability,” but zero turnover isn’t automatically a win. Some movement is healthy because it creates internal mobility opportunities, brings in new skills, and prevents teams from getting stuck in outdated ways of working. The problem is extreme churn at the wrong times, like when new hires exit within a few months, or when high performers keep leaving the same manager or department. A healthy goal is predictable, explainable turnover with strong retention in roles and teams that drive your strategy.
How do you calculate turnover for fast-growing teams without getting misleading numbers?
If your headcount changes a lot, the basic turnover calculation can still be “right” but strategically unhelpful. The fix is segmentation: track turnover separately for new hires (often measured as early-tenure turnover in the first 90 or 180 days), critical roles, and leadership, and compare each group over time rather than relying on a single company-wide percentage. You’ll also want to separate regretted turnover (people you wanted to keep) from non-regretted turnover, and to tag exits as voluntary or involuntary so you don’t confuse performance management with retention problems. This is where exit interviews and consistent offboarding documentation matter—without them, you’re guessing.
